JPMorgan Chase chief executive Jamie Dimon has admitted "regrets" to his now infamous remark from last year when the Wall Street banker called bitcoin a "fraud".

It was in September 2017 and a banking conference when Dimon called bitcoin a "fraud" that was "worse than tulip bulbs". A longstanding critic, Dimon also threatened to fire employees trading bitcoin.

Now, the high-profile Wall Street figure has backpedaled on those remarks and softening his stance in a televised interview with FOX Business Network, stating "I regret making them."

He stated:

"The bitcoin to me was always what the governments are gonna feel about bitcoin as it gets really big, and I just have a different opinion than other people. I'm not interested that much in the subject at all."
